Who Marcus is and what he edits
Marcus Reilly is the editor at Tapeboard, the operating company behind tapeboard.com, a Bloomberg-style market terminal for retail traders. As editor, Marcus is responsible for the editorial integrity of every published methodology, glossary entry, and market recap on the platform.
Editorial focus: short-side market structure, the FINRA short-volume regime, stock-loan economics, and the data lineage behind every score Tapeboard publishes. Marcus reviews the Short Squeeze Score methodology, the FINRA threshold-list rendering, the borrow-fee data feed, and the daily market-recap and most-shorted-stocks digest before publication.
Editorial principles applied to every Tapeboard page: every quantitative claim has a source citation; methodology pages are versioned and dated; AI-generated daily content is explicitly labeled and constrained to data from Tapeboard's own public APIs; corrections are issued promptly with a visible correction notice rather than silent edits. Tapeboard does not publish investment advice. Every page covering market data carries a disclaimer to that effect.
What is live and what is next
Live today. Real-time scanners across US equities, full chart workspace, options chains and gamma exposure, SEC filings with sub-90-second EDGAR latency, FRED-backed macroeconomic dashboards, the daily Short Squeeze Score (formula and weights disclosed on /methodology/short-squeeze-score), trade journal with a paper-trading simulator, and a research panel powered by Anthropic's Claude that summarizes filings without producing investment advice.
In flight. Closing-line value backtesting across the squeeze universe, Form 4 insider screener with cluster-buy alerts, and a leaner mobile read-only mode for traders who only need the morning gap board on their phone.
Honest about what is not coming. Tapeboard will not be a charting-first tool. It will not host custom Pine Script indicators. It will not route orders. It will not cover global single-name equities or fixed income. The disqualification matrix on the methodology page lists the surfaces Tapeboard is intentionally not building, and the competitor that owns each one. That list narrows the roadmap on purpose.
Who Tapeboard is not for
Reading where a tool fits is easier when the editor tells you where it does not. Tapeboard is not the right tool for the following readers.
Active scalpers who need Level 2 and order-book depth past the top of book. The Schwab retail feed Tapeboard runs on does not include ARCA or EDGX depth-of-book. If your strategy depends on reading queue position and routing inside a hidden mid-point order, the tool will not give you the surface you need. The Terminal tier exposes Schwab's Level 2 where Schwab provides it, but anything past the top of book is not in scope.
Fixed-income desks. Tapeboard does not cover bonds beyond a small set of Treasury yields pulled from FRED for macro context. Corporate credit, munis, ABS are all out of scope.
Professional advisers managing other people's money. Tapeboard is not a registered investment-adviser tool. It does not produce client-deliverable research, it does not generate audit-trail documentation that an RIA's compliance team will accept, and the AI summaries are explicitly not investment advice. If your job is fiduciary and your clients pay you to be one, the tool is not built for your workflow.
Public editorial commitments
Filings freshness SLA. Tapeboard targets sub-90-second time-from-EDGAR-publish to time-on-page for 10-K, 10-Q, 8-K, and Form 4 filings. When the desk misses the target on a material filing, the miss gets logged on the corrections page.
Refresh cadence. Comparison pages reverify every 30 days or auto-flip to noindex. Methodology pages get a quarterly review on Jan 15 / Apr 15 / Jul 15 / Oct 15. Squeeze score weights are recalibrated at most once per year, and only when an out-of-sample test justifies it. The calibration date is published in the squeeze methodology.
Correction policy. Every correction to a published claim gets a dated entry on the corrections page with the original claim, the corrected claim, and the source. Silent edits are not permitted. See the full policy on the methodology page.
Pricing. If Tapeboard's published price changes, current paid subscribers get 30 days of notice and renew at their existing rate for at least one full billing cycle.
